Reykjavik-Vik-Hofn-Keflavik in Iceland

We scheduled our car return at 5 AM. Normally, there is no staff at this time, and if the car is in good condition, you can just park it at the store and leave the keys in the box. However, we had some scratches on the car. We went to the store the day before to discuss with the staff, and they arranged for someone to inspect the car at 5 AM, issue a damage report, and told us that as long as we purchased supplementary insurance in our home country, we could relax. We would need to pay upfront, then claim reimbursement after returning home.
